A signal whose energy is concentrated in a frequency band is often referred to as a bandpass signal. There are a variety of techniques for sampling such signals, generally referred to as bandpass-sampling techniques. To examine the possibility of sampling a bandpass signal as a rate less than the total bandwidth, consider the system shown in Figure Q2(b).

Subject: Feedback and Control SystemDraw the Block Diagram of the following:2. The following very simplified model of the biological mechanism regulating human arterial blood pressure is an example of a feedback control system. A well-regulated pressure must be maintained in the blood vessels (arteries, arterioles, and capillaries) supplying the tissues, so that blood flow is adequately maintained. This pressure is usually measured in the aorta (an artery) and is called the blood pressure p. It is not constant and normally has a range of 70-130 mm of mercury (mm Hg) in adults. Let us assume that p is equal to 100 mm Hg (on the average) in a normal individual. A fundamental model of circulatory physiology is the following equation for arterial blood pressure: p = Qp Example:
